(Cl. 90-38) The presentinvention relates to high-speed the work-table is only utilized formoving the planers. Planing machines are known where the work-piece. Amachine of such an arrangement i001 during its whole stroke along itsWhole length works exactly and cleanly. It is especially suited isguided in a guide member rigidly fast to the for heavy work and bulkywork-pieces. It may Standard f the machine. Standard and guide 6 beconstructed as a one or a two pillar machine. Y
